BMW crankshaft phase eccentric shaft sensor part number 11377506503 for 1 Series, 3 Series, X1, X3 and Z4 models

This black automotive crankshaft phase eccentric shaft sensor carries the BMW-specific part reference 11377506503 and is designed for installation on compatible BMW vehicles. The sensor monitors crankshaft position and engine timing, providing critical data to the vehicle's engine control unit for proper ignition timing and fuel injection sequencing. When this sensor fails, BMW owners may experience check engine warnings, rough running conditions, or difficulty starting their vehicles, making replacement necessary to restore normal engine operation.

Features and Construction

The crankshaft phase eccentric shaft sensor is constructed with automotive-grade materials suitable for the engine bay environment of BMW vehicles. Its black colour housing helps with heat dissipation and provides visual identification that matches original equipment specifications for the listed BMW model series.

Material and Build

Built with a black sensor housing that withstands typical engine compartment temperatures and vibrations, this sensor contains internal electronic components designed to generate accurate position signals. The construction follows automotive specifications for sensors that must operate reliably in challenging thermal and vibrational conditions while maintaining signal accuracy.

Size and Practical Fit

This sensor is manufactured to match the dimensional specifications of the original BMW part 11377506503, ensuring proper fitment without modification to the engine or mounting points. Vehicle owners should note that while the broad model compatibility covers BMW 1 Series, 3 Series, X1, X3 and Z4 models, specific fitment should be verified against the exact model year and engine configuration of their vehicle.

Uses and Placement

The crankshaft phase eccentric shaft sensor serves a critical function in BMW engine management systems by monitoring the position and rotational phase of the crankshaft. This information allows the engine control unit to precisely time ignition and fuel injection events for optimal performance, emissions control, and fuel efficiency.

Event or Professional Use

For automotive technicians and repair workshops, this sensor represents a direct replacement part for BMW vehicles experiencing symptoms of crankshaft position sensor failure. Common indicators include diagnostic trouble codes related to camshaft/crankshaft correlation, intermittent stalling, or difficulty starting the engine. The specific part number 11377506503 ensures technicians are installing the correct component for the listed BMW models.

Everyday Home Use

For BMW owners undertaking their own maintenance, this sensor provides a solution when facing engine performance issues traced to crankshaft position monitoring. However, installation requires some mechanical knowledge and proper tools to access the sensor location on the engine, typically near the crankshaft pulley or flywheel area, depending on the specific BMW model.

Benefits and Buying Value

Purchasing this crankshaft phase eccentric shaft sensor offers BMW owners a component manufactured to match original specifications with the correct part number reference for their vehicle. The value comes from restoring proper engine timing signals that can affect overall vehicle performance, fuel efficiency, and emissions compliance.

Reuse and Low Maintenance

Once installed, this sensor requires no routine maintenance and is designed to provide reliable service throughout its operational lifespan. Unlike some engine components that need regular adjustment or servicing, the crankshaft position sensor typically functions without intervention until replacement becomes necessary due to wear or failure.

Why Choose This Product

This sensor offers BMW owners the advantage of the exact part number reference 11377506503, which helps ensure compatibility with their specific vehicle model. The black construction matches original equipment appearance, and the application coverage across multiple BMW series provides broad utility for owners of 1 Series, 3 Series, X1, X3 and Z4 vehicles needing this particular sensor replacement.
